The 6 craziest robots Google has acquired

That year, Google acquired seven robotics companies. There was so many to keep track of that Google spun all of its robot projects into a department called Replicant, which is run under Google X — the branch of Alphabet responsible for "moonshot projects."

We got to see a new Alphabet-owned robot this week that we think is the craziest we've seen yet. So we decided to pause and look at the tech giant's other robots.

Meka also created the Dreamer, a super cute robot with expressive eyes and ears designed to work around people.

The eyes were inspired by anime characters and the ears by puppies.

Another Alphabet-owned robotics company is Bot & Dolly, which made the 3,000-pound robot that created the effect of weightlessness in the Oscar-winning film "Gravity."

Several versions of the motion-controlled robot, named Iris, were shipped on a cargo plane to London. They moved around actress Sandra Bullock in a way that matched computer-generated sequences of a spacecraft interior or of a spacesuit hurtling toward earth, Bloomberg reported.

There's also Industrial Perception, which created the software and perception hardware that allows this robot to locate and assess the condition of the package to pick up.

The actual robot arm shown here is developed by Yaskawa, which has no affiliation with Google. But the demonstration shows how Industrial Perception can assist with software and hardware that can help robots perform tasks like sorting packages.

Google is selling Boston Dynamics, the creator of this highly functioning humanoid robot that received a lot of media attention after a video of it went viral.
